# anyHeavy {#anyheavyx}
|
||
|
||
Selects a frequently occurring value using the [heavy hitters](http://www.cs.umd.edu/~samir/498/karp.pdf) algorithm. If there is a value that occurs more than in half the cases in each of the query’s execution threads, this value is returned. Normally, the result is nondeterministic.
|
||
|
||
``` sql
|
||
anyHeavy(column)
|
||
```
|
||
|
||
**Arguments**
|
||
|
||
- `column` – The column name.
|
||
|
||
**Example**
|
||
|
||
Take the [OnTime](../../../getting-started/example-datasets/ontime.md) data set and select any frequently occurring value in the `AirlineID` column.
|
||
|
||
``` sql
|
||
SELECT anyHeavy(AirlineID) AS res
|
||
FROM ontime
|
||
```
